To log planets.join(', ') to the console, planets.join(', ') should be within the parentheses of console.log(). Calling console.log() without an argument does not log anything to the console.

console.log(planets.join(', '));

The value of planets is still ['Earth','Mars','Saturn','Mercury','Jupiter','Venus','Uranus','Neptune'], so console.log(planets) would log ['Earth','Mars','Saturn','Mercury','Jupiter','Venus','Uranus','Neptune']. The code planets.join(', '); does not modify planets; it just returns a string.
